Frequently asked questions
How do I add VAT to a price?
Multiply the net price by 1.20 for the 20% standard rate (or 1.05 for the 5% reduced rate). For example, £100 + 20% VAT = £120. The VAT element is the net price × 0.20, so £20 on a £100 net price.
How do I remove VAT from a gross price?
Divide the VAT-inclusive price by 1.20 at the standard rate — don’t subtract 20%. £120 ÷ 1.2 = £100 net, so the VAT element is £20. Subtracting 20% from £120 would wrongly give £96. At the 5% reduced rate, divide by 1.05 instead.
What is the VAT registration threshold in 2026?
You must register for VAT once taxable turnover in any rolling 12-month period exceeds £90,000, or if you expect to pass it within the next 30 days alone. The threshold rose from £85,000 on 1 April 2024 and was left unchanged by the Autumn Budget 2025. The deregistration threshold is £88,000.
What is zero-rated and what is VAT-exempt?
Zero-rated goods (most food, books and newspapers, children’s clothes, passenger transport) carry VAT at 0% but still count as taxable sales, so a business can reclaim input VAT on its costs. Exempt supplies (insurance, education, postage stamps, most financial services) are outside the VAT system: no VAT is charged and related input VAT generally cannot be reclaimed.
What is the VAT Flat Rate Scheme?
Businesses with VAT-exclusive turnover up to £150,000 can pay HMRC a fixed sector-specific percentage of gross turnover instead of accounting for VAT on every sale, with a 1% discount in the first year. You generally cannot reclaim input VAT, and "limited cost businesses" must use a 16.5% rate, which removes most of the benefit.
